The concept version features sculpted contours that showcase Infiniti's "dual wave" effect. Other details include 21-inch wheels and larger-profile tires, along with roof racks that provide a major design cue.

"They provide a 'sculpture' for the rear passengers to look through, resulting in an unusual perspective of the world outside," said Infiniti in a statement on Thursday.

It is unclear whether these elements will be part of the production version.
